I don't think the current Vortex cards make for a great half. These new decks are all extremely overrated, imo.

They're decent, certainly playable, but the fuss that's being made about them doesn't reflect the actual potential of the cards.

Piranas make one of the best combinations, and this version is one of the better presets, but we're going to have to wait to see the clan's full potential and, in turn, the kind of decks that will really shine.

Unoposed are they not good for 1 pill blufs? or zero pill? and I dont really get the system but I know if you have 6 pills total then you would get 4 back thats pritty overpowered because you can put on 8 and get 5 back? so your opponent loses and you have apill advantage?

You only get your pillz back if you lose, it takes some savvy to make the best of that, since a smart opponent might not pill and let you waste your eight pillz.
And yes one pill bluffs, and third round gambles are where the Vortex clan really shines.
